Low-cost radon monitoring with validation by a reference instrument
Abstract This article reports radon tracing using a low-cost, locally manufactured smart electronic device with comparison to a reference device. Developed for radiation protection and nuclear security, the proposed device consists of a ZP 1200 Geiger-Müller (GM) tube detector with low-cost components including an Arduino microcontroller board, a DHT11 temperature (T) and relative humidity (RH) sensor, and XBee-based Internet of Things (IoT) wireless transmission modules. The reference device measures radon concentration, temperature, and relative humidity in indoor spaces. Typically, the developed device provides data of atmospheric parameters (T, RH) and the ambient dose equivalent rate H*(10). From the ambient dose equivalent rate in µSv/h, the radon activity concentration (in Bq/m3) is determined using standard and recognized conversion coefficients. The coefficients vary according to the ambient radiation strength and range from 5500 to 8900 (Bq/m3)/(µSv/h). The developed device and the reference instrument were used for one month in several dwellings in the city of Yaoundé-Cameroon. Periodic average values of 27.5 ± 2.0 °C (developed device) and 26.2 ± 2.0 °C (reference) for temperature, 74.1 ± 6.4% (developed device) and 73 ± 6% (reference) for relative humidity, and 1500 ± 163 Bq/m3 (developed device) and 1465 ± 164 Bq/m3 (reference) of cumulated radon activity concentrations were obtained for a 24-hour period. Statistical analyzes carried out on the results of the devices provide a linear regression coefficient of R2 = 0.9978, demonstrating good agreement between the instruments.
期刊介绍:
Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community.
Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more.
Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
